by ATG in the United Kingdom at Cardington. SkyCat group After ATG went into administration, its assets were acquired in 2006 by an Italian–British consortium and the new business named SkyCat Group. However, SkyCat Group itself went into administration about a year later. Hybrid Air Vehicles The assets of the SkyCat group were acquired by a new firm, Hybrid Air Vehicles (HAV), set up by British investors in 2007. HAV and partner Northrop Grumman won a $517 million LEMV contract to build three Hybrid Air Vehicles HAV 304 hybrid airships for the US Army in Afghanistan. The first one flew in 2012 but the project was terminated the next year in a round of US defence cuts. HAV re-purchased the envelope of the HAV 304 and returned it to the UK, where they refurbished it for civilian use as the Airlander 10. Airlander 10 completed design certification testing before being written off when it came loose from its moorings in a high wind on 18 November 2017 at Cardington Airfield.
